One of the participants on the railcar meeting 2018 at Bauma was former Südostbahn "Glaskasten" railcar ABe 526 # 290 (former ABe 4/4 # 11) "Burghalden". This 735 kW railcar was built in 1939 as CFZe 4/4 # 11 by a consortium of SLM, SIG, SWS, MFO, BBC and SAAS. This vehicle is used today by association "Tunnelkino" for cinema events in the Weissenstein tunnel between Oberdorf and Gänsbrunnen.
